In her most recent Instagram post for Valentine's Day, Duggar followers continued to speculate whether Joy-Anna, 20, and Austin, 24, had sex before tying the knot last May. However, some fans quickly came to the couple's defense. "Her due date is on February 22, 2017 her conception date was on June 1st, 2017 and her wedding was on May 27, 2017. If anyone have [sic] doubt just check on Google reverse conception date," one person wrote before another added, "This would have happened most likely wedding night. May 26th. Like I said during the first week."

Earlier this month, fans of the reality star couple went as far to speculate that Joy-Anna was posting old photos to hide that fact that she already gave birth. Along with sparking premarital sex rumors, Joy-Anna's big baby bump also has follower crossing their fingers for twins. "She's got to be having twins," one comment read on her Instagram page before another follower responded, "I am also team twins." Joy-Anna has not spoken out about the rumors.

Joy-Anna and Austin first shared the exciting baby news last August. "We’re so happy and thankful to announce that we’re expecting a baby," the couple told People. "Every child is such a precious gift from God. I’m most looking forward to watching Austin as a dad and raising children together with him." However, she's not the only Duggar sibling with a tiny bundle of joy on the way.
